The UN-sponsored panel's report is a comprehensive analysis for policymakers, written and reviewed by some 900 scientists who looked at more than 9,000 studies on climate change.
In a message to the conference in Stockholm, Ban Ki-moon, secretary general of the UN, said: "Since 1990 the IPCC has provided regular, unbiased assessment of the mounting impact of a warming planet.
"You are the world's authorities on climate change, recognised with a Nobel Peace Prize."
He added that "we need to build resilience and seize the opportunities of a low-carbon future".
"The heat is on. Now we must act," he said.
